We studied the microbiological quality and prevalence of Vibrio parahaemolyticus in finfish and shellfish sold in the domestic markets of West Bengal, India following enrichment in alkaline peptone water and further plating on to thiosulfate citrate bile salt sucrose agar. Total plate count of bacteria in shrimp flesh with the exoskeleton, and finfish muscle with skin was also estimated which ranged from 20±1.12 x 105 cfu/g to 73±1.12 x 105 cfu/g, and from 0.2 ±0.18 x 105 cfu/g to 1.2 ±0.43 x 105 cfu/g, respectively. Prevalence of V. parahaemolyticus varied in different fish and shellfish species, with highest prevalence in Lutjanus sp (27.77%) and lowest in Setipinna phasa (10%); the bacterium was not detected in Labeo bata and Channa striata. The contamination rate was higher in shellfish like Penaeus monodon (42.85%) and P. indicus (40%).Contamination was higher during summer than in winter: an average of 20.85 % of finfish and shellfish were contaminated during winter, compared to contamination of 31.45% of samples during summer months. The study showed that although overall microbial load was within permissible limits, fish and shellfish were contaminated with V. parahaemolyticus raising food safety concern to the domestic consumers.
